Orcheetes, | RHYNCHOPHORA, 263 
and most likely general; it appears to be more widely distributed but less common 
where it occurs than several of the other species. 
O. saliceti, Payk. This very small species differs from all the 
others found in Britain in not having the posterior femora sensibly 
dilated ; in this respect it resembles O. populi, a larger species, which 
occurs in Northern, Central and Southern Europe, and has been wrongly 
introduced into our lists by Stephens (and on his authority referred to 
Britain by M. Brisout), on specimens of O. stigma, in which the posterior 
femora are comparatively slightly dilated ; subovate, black, rather 
shining, slightly pubescent ; head opaque, finely punctured ; rostrum 
shining, delicately punctured ; anternz red, with the club dark, inserted 
a little behind middle of rostrum, funiculus seven-jointed ; thorax 
scarcely transverse, convex, strongly and not closely punctured, with the 
sides rounded, hardly narrower at apex than base ; elytra oval, much 
broader than thorax, with very strong and deep punctured strie, inter- 
stices almost narrower than the strie, convex and shining ; femora 
black, tibia and tarsi red, the latter sometimes pitchy ; the species has 
more the facies of Tanysphyrus than of an Orchestes and certainly seems 
distinct generically at first sight. L. 13; mm. 
On various willows and sallows (Salix cinerea, alba, caprea, &c.); local and, as a 
rule, not common; Putney (Champion); Suodland, Kent ; Wimbledon Common 
(S. Stevens); Hammersmith (Power); Norfolk and Somersetshire (Stephens) ; 
Portsmouth district (Moncreaff) ; Repton, Burton-on-Trent (W. Garneysand myself) ; 
Chat Moss (Chappell) ; Southport (Reston) ; Northumberland and Durham district 
(Bold) ; Scotland, local, on sallows, Solway, Tweed, Dee and probably other districts 
(Sharp); Ireland, Glasnevin, near Dublin (McNab’s list); it appears tu be very 
scarce in the Midland counties, but to become commoner in the North. 
RHAMPEHUS, Clairville. 
The members of this genus are small insects which closely resemble 
Orchestes, but differ in having the antennz straight and inserted at the 
base of the rostrum between the eyes, and the upper surface of the 
body glabrous, and by the very short scape of the antenne ; the anterior 
cox are plainly separated ; about four are known, which all inhabit 
Europe ; the larva of the single British species is found on the leaves of 
various trees, willow, apple, cherry, birch, &c. 
R. flavicornis, Clairv. (pulicarius, Herbst.). Obovate, rather 
depressed, black, glabrous, shghtly shining; antenne ferruginous or 
reddish testaceous, with the club, which is rather elongate, dark ; 
scape very short, shorter than the first joint of the funiculus, which is 
globose-ovate ; thorax transverse, narrowed in front, with distinct 
punctuation, which is scanty, as a rule, on disc; elytra with strongly 
punctured striz, interstices narrow and flat; legs entirely black, 
posterior femora rather strongly thickened. L. 1-14 mm. 
On willows, cherry, birch, apple, &c.; locally common throughout the greater 
part of England and Wales; Scotland, local, Solway, Tweed, Forth and Moray 
districts ; Ireland, Dublin, Queenstown, Waterford and probably general; it appears 
to be found in most localities in the Midland counties of England.
